THE NEA/V COASTER-BFAKE.

hij' invention relaies lo improvements in coaster brakes, e

.One object is to provide for the easy insertion ol the coaster brakehnh in the freine ol? a bicycle and the easy removal of 'the sainetherefrom.

Amother object is to provide for the renio 'ul of the coaster brake hubfrom the bicycle riune without the disturbance oit the adjustment of theparts of such coaster hralie. mechanism.

To these ends und also to improre genernlly upon devices of thecharacter indi-. willed, my invention consists oli' the ferions mattersherein described and claimed.

ln the accompanying drawings:- Fignre l is n setlionnl elevation, e.portion of the freine of n. bicycle being illustrated; Fig. is nnelemtion of certain ot' the parte Aupon substantially thc line 2-2 ofFig. l, the brake-actuator und the axle being' shown in section and nportion of the bicycle frame being' indicated; Fig'. 5l is nn endelevation ci the brake-actuation und Fig. eL is n` side elevation ofi'he suine.

My invention is here illustrated in connection with n mechanismgenerally siinilnr in construction and ope'ntion to that, disclosed inpatent to Rockwell, No. 745524:, to which reference isnnide for a moredetailed explanation of the general structure.

The :tile 2 is supported upon the bicycle :traino sind the hub-shell 3rotates about the sume. Said huh-shell, the threaded driver ll, lhe.laterally shiftnhle clutch sleeve 1f), the lng springt 26, and the cone8 nre sul)- stnntinlly similar in construction und operation lo theCorrespending;r parte disclosed in the said patent to Rockwell. Also,the brake-plate 4T, the ln'nke-ring' supported hy smid plate, and theln'zike-actinitor i6 are generally similar to the corresponding parte inthe Suid Rockwell patent, there Specification of Letters iT-etant.
